using variables in admin mail notification was created by Siem
In an admin mail notification I want to display some scores.
It would be very handy if I could use variables. These variables are not defined in the survey.
Below is an simple example, how would I do that?
Code:
{ $a = 5 } // nothing is printed here
{ $b = 6 } // nothing is printed here
{ $c = $a + $b } // nothing is printed here
{ print($c) } // "11" is printed in the mail.

Maybe I don't understand the question correct, but you can use Expression Manager code in the admin mail notification, which can be used to display scores.

I can use the Expression Manager code there.
Basicly I want to know how to use variables in the Expression Manager (if that's possible). Should I define these variables first?

If the variables are not defined within the survey, where does the data come from? If it is no dynamic data, why can't you hard code it within the text?

I could hardcode it in the text, but the code is quite long. Certain long calculations are done multiple times within different formulas.
So in order to keep it sane, variables could be handy.

You can use variables by adding "equation" questions at your survey. Just enter the variable value at the question text and use the question code as variable name.
You can then use the Expression Manager for calculations like:
{(a.NAOK + b.NAOK) / c.NAOK}

In Expression manager, unlike JavaScript and other languages, you cannot simply declare and define variables. Variables are only question or sub-question answers, token attributes or a few other survey parameters so, as Mazi says, must be defined in the survey.

Thanks that's clear. For now I will skip the variable part then and make my formula's longer.

There's only one last hurdle for me to make that work: how would you make the (simplified) examples below valid?
Code:
{ if ( countif(Q1=='A1',Q2=='A1',Q3=='A1',Q4=='A1') > 1, 'more than one' , 'not more than one') }
{ if ( ( countif(Q1=='A1',Q2=='A1',Q3=='A1',Q4=='A1') - 2 ) > 1, 'more than one' , 'not more than one') }

It seems to me that should be something like:

Code:
{if(sum(Q1=='A1',Q2=='A1',Q3=='A1',Q4=='A1') > 1, 'more than one' , 'not more than one')}
{if((sum(Q1=='A1',Q2=='A1',Q3=='A1',Q4=='A1') - 2) > 1, 'more than three' , 'not more than three')}
